Rest API - HTTP Methods

What will be the result of sending two identical PUT requests to update a user's name?

PUT /users/5 {"name": "Alice"}
PUT /users/5 {"name": "Alice"}

AThe server returns an error on second request

BThe user's name changes twice

CThe user's name is deleted after second request

DThe user's name changes once, second request has no effect

Step-by-Step Solution

Solution:

Step 1: Understand PUT idempotency
PUT replaces the resource with the same data each time, so repeated requests do not change the state after the first.
Step 2: Analyze effect of two identical PUTs
The first request updates the name; the second request sets the same name again, causing no change.
Final Answer:
The user's name changes once, second request has no effect -> Option D
Quick Check:
Repeated PUT = same resource state [OK]

Quick Trick: PUT with same data repeated does not change resource again [OK]
